From Norfolk Developers – Nor(DEV)


# The Very Slow Time Machine with Jez Higgins

Archangel is a joint project involving University of Surrey, The National Archive, and The Open Data Institute, investigating how we might help ensure the long-term integrity of digital documents stored in public archives.

When an archive produces a physical artefact, its relatively easy to establish that it is indeed the original document, preserved unaltered since it was first deposited.

But a _digital_ artefact?

A digital document can be infinitely copied without degradation, but can also be undetectably altered, inadvertently or deliberately, both with benign or malign intent.

How can we be confident that what we’ve presented with is, in fact, identical to the document that was first stored in archive?

Archangel is trying to address this problem, and in this talk I’ll describe some of the approaches and technologies we’re using.

Spoilers: Yes, it includes blockchains, but it’s about the only blockchain application you’ll hear of that doesn’t immediately make you feel dirty. It might also include machine learning, but it’s machine learning for justice.

## Jez Higgins

You may know Jez from such talks as A Browse Through ES6 or Chris & Jez’s Old Skool Artisan Software Workshop. He’s currently working for West Midlands Fire Service as software grandad-in-residence and on Archangel as a researcher, although by the time this talk rolls round he’ll be looking to start filling his 2019 diary.

# How to make login constant time and why it’s important

What it says on the tin. In a practical session we’ll look at the implications of variable time logins and how we can stop it using simple techniques. Live coding in Go with the added benefit of learning about goroutines and bcrypt at the same time.

## Dom Davis
Not wanting to be outdone by Jez, Dom is choosing to use a single black pixel for his profile picture (nothing to do with the fact that MeetUp wont let us put in multiple pictures and most of you know what I look like anyway). Dom is a regular speaker for NorDev with a flippant style that he likes to think makes complex topics approachable. whether this works is up for debate.
